How to Write a UK Phone Number: Codes for Dialing UK Numbers

You should understand the proper format and specific dialing codes while writing or dialing a UK phone number. The format used in UK numbers is a single digit with clear differentiation of the area code and the subscriber number. 

UK multiple area codes range from 3 to 5 digits. When you dial a UK number from another area but within the UK, just dial a ‘0’ before the area code and phone number. Dialing the country code is not necessary. However, country code +44 is used with the phone number if you call from outside the UK.

There are codes for dialing the UK numbers. They are as follows:

1. Three-Digits Code

The three-digit dialing code in the UK always starts with 02, followed by eight-digit phone numbers. A list of three-digit UK dialing codes is given as:

AreasCodes
London020
Coventry024
Southhampton and Portsmouth023
Cardiff029
Northern Ireland028

When dialing from the UK, the three-digit area code will look like (020)-XXX-XXX. If you call from a foreign country, the three-digit area code will be +44-20-XXX-XXX.

2. Four Digits Code

The four-digit dialing code starts with 011X or 01X1. After dialing the area codes, you should dial the 7-digit subscriber number. Large cities usually follow the four-digit code. When calling within the UK, the four-digit area code will be 011X-YYYY-YYY or 01X1-YYYY-YYY

But, if you are dialing from another or a foreign country, the four-digit code will be +44-1XX YYYY-YYY. Some of the UK areas and their codes are:

Castleford01977
Chesterfield10246

4. International Dialing Code

Using ‘+’ in front of the international dialing code would be more appropriate as customers will understand that they must enter their specific country code. The country code for directly dialing the UK from anywhere in the world is +44.

To connect to another country, you can use the International Direct Dialing (IDD) code, which for the UK is 00. For example, dialing a number from Australia to the UK will look like 00-61-2-98765432

The breakdown of the numbers is 00 (IDD number for the UK), 61 (Australia country code), 2 (Sydney area code), and 98765432 (Australian phone number).

  1. Enter the landline number: Finally, enter your contact’s number after entering the access code, country code, and area code. Press the call button and initiate the call.
